Installed my plenum and P.P 70mm throttle body today and now my car won't start. She turns over and revs a little high then just dies. If I give it gas it will stay on but as soon as I quit it dies. From everything I read the cars should idle rough for ten mins, or so until the computer readjusts for the added air. The only thing I could think of is a vacuum leak but I have no other idea. Anybody ever have anything like this going on? Thanks in advance for any and all advice.
